Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 232-455-8 | CAS number: 8042-47-5 A highly refined petroleum mineral oil consisting of a complex combination of hydrocarbons obtained from the intensive treatment of a petroleum fraction with sulfuric acid and oleum, or by hydrogenation, or by a combination of hydrogenation and acid treatment. Additional washing and treating steps may be included in the processing operation. It consists of saturated hydrocarbons having carbon numbers predominantly in the range of C15 through C50.

Key value for chemical safety assessment
Additional information
Viscosity for highly refined base oils is >3 mm2/s at 40°C and >1.3 mm2/s at 100°C (CONCAWE, 2010a). Viscosity was determined using the ISO 3104 test method.
Additionally, highly refined base oil viscosities may be characterised by measured values for several samples, which range from 3.08 to 11 mm²/s at 100°C (CONCAWE, 1997). Viscosities were determined according to the ASTM D 445 test method. An assessment of the composition and physical-chemical properties for ten samples of food-grade white oils reported viscosity values ranging from 14.2 to 73.5 mm²/s at 40°C (CONCAWE, 1984). Viscosity values for white oil (CAS # 8042-47-5) have also been reported to range from 13.3 to 99.8 mm²/s at 40°C (CONCAWE, 1993). In another study, four highly refined white mineral oils were reported to have viscosities ranging from 26.5 to 103.7 mm2/s at 40°C (Haus et al., 2003).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
